CalArts Student Experiments with 3D Printing Light

Not all 3D printing is meant to last. When CalArts student Aaron Bothman decided to print something for his short film The Red Witch, his thesis project, he wanted it to be less permanent. Having seen the work of Beijing-based artist Ekaggrat Singh Kalsi, who has used a modified 3D printer to ‘print’ in light, he found his inspiration.

Not something that you can pick up with your hands, the product of this technique is something that can be captured on film, which is exactly the medium in which Bothman works.

He and his father worked together on building the printer, a small delta model constructed from a kit but with a particular twist. When assembled, an LED was placed where the hot end would usually have been installed. This allows Bothman to capture the light on film by using a long exposure while the printer runs the model, tracing out the shapes as a 3D light painting.

This isn’t the first 3D printing project that Bothman junior and Bothman senior have worked on together. In an interview with 3DPrint.com, Aaron talked about his experience printing with his father and how it has influenced his work both while at CalArts and after graduation:

“I’m an animator and artist based in Los Angeles. I graduated from the animation program at CalArts a couple months ago, and am currently working as an artist at JibJab, a small studio in LA. I originally learned about 3D printing in middle school from my dad, who teaches mechanical engineering at UCSB, and who helped a lot in thinking through this project. As a stop-motion filmmaker, 3D printing allows me to tackle more ambitious projects on a short production schedule than I might be able to otherwise.”

In order to create the light animation, each Maya image to be captured is sent to the printer one frame at a time. Over time, these images create the illusion of movement, just as is done in more traditional stop motion filming. The result is a piece that is built up in layers, requiring the same mode of conceptualization as a 3D printing project but with the option for movement and, of course, no support materials. In fact, no materials at all, something that makes this a particularly appealing way to engage in a 3D printed project if there is no need for the product to be tangible.

Somewhat akin to the old question about a tree falling in the forest with no one to hear it, the question that could be asked of this technique could be: when a 3D printer creates something that cannot be touched, is it still 3D printing? The creations don’t truly occupy space or at least they only do for a fleeting moment but as they dance before your eyes, I think you may be willing to set that debate aside for a moment. Just think of it this way: with this technique, you could print all you want and never run up a bill for filament and never have to worry about storage space.

And that sounds pretty ideal to me.

3D Printing with Light has Finally Happened!

What if you could just print light on whatever you wanted? We’re watching 3D printing make progress in nearly every arena, so using it for creating one of the most basic needs we have on a daily basis seems only logical.

We’ve long been using creations of light based on inventions from historical geniuses and technological giants. Today though, as 3D printing advances, you will be headed in the direction of printing your own lighting with the help of US-based Rohinni and their new product, Lightpaper.

While we aren’t quite ready to unscrew all the lightbulbs in the office and throw them out, the idea of replacing them eventually with thin sheets of 3D printed light is a stunning consideration.

With 3D printing being conducive to embedding a multitude of different technologies and electronics, 3D printing with light should prove to offer new innovation and flexibility for manufacturers. While Rohinni does have mild competition in the area, they do have one completely unique factor: Their product is razor thin. And flexible. And 3D printable.

According to Rohinni, the emergence of printable light is on par with 3D printing in terms of new possibilities and application potential. With a number of different mindblowing and innovative methods used to merge technologies with 3D printing and electronics, this form of lighting, which can be produced rapidly and affordably, could offer use and advancement in various applications for consumer products, and specialized areas such as automotive, for headlights.

They are the only company working to 3D print paper using an innovative method combining ink and tiny LEDs which are printed out on a conductive layer and then sandwiched between two other layers, lit up with LED current.

Light goes hand in hand with technology, and often creates that wow factor because, quite simply, it catches the eye. Rohinni is working to spotlight their technology in a bid to gain the attention of industry movers and shakers who would benefit from its applications.

OLED (organic light emitting diodes) technology is a competing force for this product, in their use of LED technology in a series of thin, light emitting films, most commonly used to power televisions these days. But Rohinni’s eventual mainstream direction will be for backlighting for gadgets and everyday objects.

With the goal for Lightpaper to be available to the hobbyist market eventually, 2015 is the target date to bring the 3D printed light source to the commercial and industrial marketplace. They are currently still working to streamline and perfect the product.

Is this something you have thought about that would work with the technology of 3D printing? What do you think this will be useful for in particular? Tell us your thoughts in the World’s Thinnest Light forum over at 3DPB.com.
